* Shell CEO remuneration was $5.6 mln in 2015
* Pay disconnected from Shell's performance - Glass Lewis (Adds Shell comment)

LONDON, May 17 (Reuters) - Two investor advisory firms haverecommended Royal Dutch Shell shareholders oppose theCEO's 2015 remuneration, in the latest sign of rising discontentover pay amid falling oil prices.
Shell Chief Executive Ben van Beurden's 2015 remunerationfell 8 percent to 5.135 million euros ($5.63 million) last year,when the company's revenue dropped sharply due to low oilprices.
Proxy adviser Glass Lewis said in a report it remains"concerned by the disconnect between bonus payouts and financialperformance, and the bonus scheme structure more generally".
In a separate report, adviser PIRC said "the ratio of CEOpay compared to average employee pay is 37:1, which isunacceptable".
Both firms recommended shareholders oppose the remunerationpackages in a vote at Shell's annual general meeting in TheHague next week.
A Shell spokesman said Shell's executive compensation"reflects delivery of our strategy, measured by both short-termand long-term targets. There is a clear alignment between thecompany's performance and our compensation policies".
Shareholders have become increasingly vocal over executivesalaries and bonuses amid slumping earnings and lower commodityprices.
Last month, BP's shareholders voted against ChiefExecutive Bob Dudley's $20 million pay deal for 2015, a rareinvestor revolt for such a major company, after it recorded arecord annual loss.
Van Beurden's total 2015 package, including pension and taxequalisation, was 5.576 million euros, down from 24.198 millioneuros in the previous year, mainly due to a significant fall invan Beurden's pension which was positively affected in 2014 bypromotion to chief executive.
In April last year, Shell launched a bid for smaller rivalBG Group which it completed in February this year for $54billion. (Reporting by Ron Bousso; editing by Susan Thomas)
